Bishop Michael Bransfield of Wheeling-Charleston, West Virginia, says allegations that he sexually abused a teenage boy are "unbelievable and shocking," as well as completely false.

The accusations were raised by a witness at the trial of two Philadelphia priests on sex abuse-related charges. The witness said another Philadelphia priest who has since been removed from ministry told him about the alleged abuse by Bishop Bransfield.

The allegations surfaced during the fourth week of the trial of a priest who is accused of the attempted rape of a 14-year-old boy in 1996, and Msgr. William Lynn, who is charged with failing to protect children while serving as secretary for clergy in the Archdiocese of Philadelphia.
